Decomposing rural-urban gap in unsafe disposal practice of child stool in India using nationwide sample survey data

A significant rural–urban disparity in unsafe child stool disposal practices exists in India, yet existing research falls short in identifying the contributing factors to this gap. This study addresses the research gap by contextualizing the rural–urban divide in unsafe child stool disposal using data from the fifth round of the National Family Health Survey (NFHS-5, 2019–21). In particular, the study examines the prevalence and predictors of unsafe disposal practices, exploring associated contributing factors to this gap. The study involves a sample of 78,074 women aged 15–49 with a living child under 2 years, without any missing data related to the study interest. Employing descriptive statistics, the Pearson chi-square test, multilevel logistic regression, and the Fairlie decomposition model, the research aims to fulfill its objectives. The rural–urban gap in unsafe child stool disposal practices among the study participants was 22.3 percentage points (pp), with a more pronounced gap among the Scheduled Tribes (ST). Notably, the gap was particularly wide in Madhya Pradesh (33.9 pp), Telangana (27.5 pp), Gujarat (26.1 pp), and Rajasthan (25.8 pp). Predictors such as mother’s education, mass media exposure, household wealth quintile, and sanitation facilities proved significant irrespective of residence. However, religion, social group, and water facility on household premises emerged as significant factors in rural areas only. The study identified that 67% of the explained gap in unsafe child stool disposal practices was attributed to the rural–urban difference in household wealth. Other noteworthy contributors were ‘household sanitation facility’ (21.3%), ‘mother’s education level’ (3.9%), and ‘water facility on household premises’ (3.9%). These findings underscore the need for population and area-specific policy interventions, especially for individuals from socio-economically disadvantaged backgrounds, those with lower education levels, and limited exposure to mass media, particularly in states with a high prevalence of unsafe disposal practices. Such interventions are crucial to mitigating the existing rural–urban gap in unsafe child stool disposal practices.

While commendable progress has been observed in the use of improved sanitation facilities among adults in India, a noteworthy public health concern persists regarding the unsafe disposal practice of young child stool 1 .The latest National Family Health Survey (NFHS), conducted from 2019 to 21, highlights that despite 61% of households in India using improved toilet facilities, only 36% followed safe disposal practices for their child's stool 2 .Therefore, these statistics suggest that existing sanitation programs have predominantly focused on enhancing sanitation coverage and practices among adults, inadvertently overlooking the safe disposal practices of child stool 3 .Safe disposal practices for child stool include placing or rinsing the child's stool in a toilet or latrine, burying it, or having the child use a toilet or latrine 2,4,5 .In contrast, unsafe disposal practices of child stool involve depositing or rinsing them into a drain, ditch, bush, garbage heap, or leaving them on the ground 5 .A recent study covering 34 low-and middle-income countries (LMICs) showed that half of households practiced unsafe disposal of child stool in this region 6 .The prevalence of unsafe disposal practices of child stool was found to be considerably high in India (64%), exceeding the LMICs average (50.6%).Although the prevalence of unsafe disposal practices for child stool remains high in India, there has been a considerable decline from

Data source
The present study utilized secondary data from the fifth round of the NFHS, conducted during 2019-2021.The NFHS-5 survey collected comprehensive data on reproductive and child health, public health, family planning, and others 2 .The NFHS-5 sample was strategically designed to offer national, state/union territory (UT), and district-level estimates for various population and health-related indicators crucial for monitoring the Sustainable Development Goals (SDGs) 2 .However, certain indicators, such as sexual knowledge and behavior, domestic violence, and men's health indicators, are designed at the state/UT and national levels.Furthermore, NFHS-5 also included several indicators, including vital events, preschool education, and child stool disposal 2 .

Sampling design
NFHS-5 used a two-stage stratified sampling technique to select a representative sample of households for data collection 2 .In the first sampling stage, the country was divided into geographical units known as Primary Sampling Units (PSUs).These PSUs were selected using probability proportional to size (PPS) sampling, where the size of the PSU was based on the population.The PSUs were selected from rural and urban areas separately to ensure proper representation of both settings.Within each rural stratum, PSUs were selected based on the literacy rate of women aged 6 + years.Within each urban stratum, a sample of Census Enumeration Blocks (CEBs) was selected as PSUs based on the scheduled castes and scheduled tribes (SC/ST) population.In the second stage, a complete listing of households was carried out in the selected PSUs.A fixed number of 22 households per cluster were selected with an equal probability of systematic selection from a newly created list of households in the selected PSUs.From the household listing, a systematic random sample of households was selected 2 .This involved selecting a starting point at random and then choosing every "k-th" household from the list, where "k" was a predetermined interval.In all, 30,456 Primary Sampling Units (PSUs) were selected across the country in NFHS-5 drawn from 707 districts, of which fieldwork was completed in 30,198 PSUs.Within each selected household, specific individuals were identified for various interviews.A random selection process was used to identify eligible respondents within the household.After the sample was collected, it was weighted to the data to adjust for any discrepancies between the sample and the larger population.This ensures that the survey results accurately reflect the characteristics of the entire population.The details of the respondent selection strategy and sampling weights are available in the NFHS report 2 .NFHS-5 utilizes four survey instruments to encompass a range of health and well-being concerns.These instruments comprise various questionnaires linked to general households, male health, female health, along with clinical, anthropometric, and biomedical (CAB) assessments 2 .In NFHS-5 (2019-21), a total of 653,144 occupied households were selected for the sample, of which 636,699 were successfully interviewed, with a 98% response rate 2 .A total of 747,176 eligible women between the ages of

Outcome variable
The outcome variable was disposal practice of children's stools.This variable exhibits a dichotomous nature: safe disposal and unsafe disposal.Safe disposal practice of children's stools is considered when the child uses a toilet or latrine, when the fecal matter is placed or rinsed into a toilet or latrine, or when it is buried 2 .In contrast, unsafe disposal practices involve leaving fecal matter in open areas, disposing of it in garbage bins, rinsing it into drains, or employing alternative methods.The sub-categories of the outcome variable correspond to the latest NFHS-5 report, prepared by the International Institute for Population Sciences (IIPS) and the Inter-City Fund (ICF) 2 .

Explanatory variables
In line with previous studies in India and elsewhere 10,11 , the present study selected a set of explanatory variables, including respondent's age and education level, religion, social group, place of residence, household wealth quintile, mass media exposure, drinking water facility on household premises, household sanitation facility, and region.A detailed description of explanatory variables is presented in Supplementary Table 1.

Statistical methods
Descriptive statistics (percentage distribution with 95% confidence interval) were used to describe the background characteristics of the study participants.A bivariate analysis was used to present the prevalence of unsafe disposal practice of children's stoolsby selected explanatory variables.In addition, Pearson chi-square test was appliedto examinethe significance level of the bivariate associations.All descriptive results based on weighted sample using NFHS sampling weight.Sampling weights are employed to manage and regulate the proportional contribution of each participating unit, ensuring an accurate representation in the overall population estimate.The details of the sampling weight available in NFHS report 2 .The present study also calculated the absolute rural-urban gap in unsafe disposal practices of children's stools, considering selected background characteristics of the study participants.Further, two separate multilevel logistic regression analyses wereperformed to identify www.nature.com/scientificreports/ the significant predictors of unsafe disposal practice of child stool and geographical variation in the predictors.It's noteworthy that the NFHS dataset follows a hierarchical structure, with respondents nested within households (HH), households nested within primary sampling units (PSU), and these PSUs further nested within districts 2 .A random intercept logistic regression model was used for the current investigation 19,20 .The model has been selected for the likelihood of a mother withchild aged 0-24 months (i) in the HH j, PSU k, and district lpracticed unsafe disposal of child stool (Ƴ ijkl = 1) in rural areas, and same model replaced to study participants in urban areas.
This model calculates the log odds of π ijlk adjusted for vector X ijkl of predictor variables assessed at the individual level.The parameter β o indicates the reference category of all variables with log odds of the unsafe disposal of child stool.The random effect within the parentheses is measured as a residual differential for the district l (f 0l ), PSU k (m 0kl ), HH j (p 0jkl ), and individual i (s 0ijlk ) considered to be independent and normally distributed with mean 0 and variance σ 2 f 0 , σ 2 m0 , σ 2 p0 , and σ 2 s0 , respectively.The variances quantify between districts, between PSU, and between households, respectively, in the log-odds of unsafe disposal.The multilevel model results were presented in adjusted odds ratio (AOR) with 95% confidence interval (CI).Finally, the present study performed the Fairle decomposition model to contextualize the rural and urban gap in the unsafe disposal of children's stools.The present study utilized a binary-model-appropriate version of the Blinder-Oaxaca approach, developed by Fairlie 21 , to decompose the rural and urbangapin the unsafe disposal of children's stools.
The decomposition for a non-linear equation y = (xβ) can be written as: where N J is the sample size for interest group j. y j is the average probability of the binary outcome of the interest group j, and F is the cumulative distribution function from the logistic distribution.Here, superscripts O and S stand for rural and urban.The first term in brackets in the equation above represents the part of the gap between groups due to group differences in distributions of the entire set of independent variables, and the second term represents the part due to differences in the group processes determining levels of y.Explanatory variables underwent multicollinearity testing using variance inflation factors (VIF) before the decomposition analysis.Importantly, no evidence of multicollinearity was found (VIF < 2).Details of the Fairlie decomposition model available in previous literatures 21,22 .All statistical analyses were performed on STATA 12 SE software (Stata Corporation, College Station, Texas, USA).

Background characteristics of the study participants
Table 1 presents the background characteristics of the study population by place of residence.Most of the mothers were aged between 20 and 29 years in both rural and urban areas.Higher-educated mothers were more than two-fold higher in urban settings than their rural counterparts (30.4% vs. 12.6%).Most of the respondents were Hindu and belonged to the Other Backward Class (OBC), irrespective of the place of residence.However, the percentage of respondents belonged to ST social category was relatively low in urban settings compared to rural counterparts (4.4% vs. 12.7%).The percentage of the poorest households was noticeably higher in rural areas than in urban counterparts (30.8% vs. 4.2%).The respondents with no exposure to the media were nearly three-fold percentage points higher in rural areas (34.3%) than in urban (12%) counterparts.About 30% of households in rural areas had no water facility on the premises, whereas in urban areas, it was 17.9%.Open defecation practice was prevalent in rural areas (29.2%) than in urban (7.3%) counterparts.A detailed tabular presentation of study participants by type of disposal practice and place of residence is presented in the Supplementary Table 2.

Rural-urban gap in prevalence of unsafe disposal practice of child stool
In the study population, the rural-urban gap in the prevalence of unsafe disposal of child stoolwas 22.3 percentage points (pp) at the national level (Table 2).Similarly, the gap also varied across different demographic and socioeconomic backgrounds.For instance, the rural-urban gap in the unsafe disposal practice of child stool was substantially higher among mothers aged 30 years and above (26.6 pp) than their counterparts.Among mothers with no education, the rural-urban gap in the unsafe disposal practice of child stool was about 20.4 pp.Similar results were also observed among mothers with primary and secondary education levels, with the gap ranging between 20.9 pp and 19.8 pp.The rural-urban gap in the unsafe disposal practiceof child stoolwas higher among the Hindus (23.9 pp), followed by the Muslims (18.1 pp).The unsafe disposal practiceof child stool was considerably higher among the ST individuals than their counterparts in rural areas, indicating a higher rural-urban gap (28.5 pp).The rural-urban gap in the unsafe disposal practice of child stool varied across the household wealth quintiles (range: 3.0 pp to 7.1 pp).In particular, the prevalence of unsafe disposal practice of child stool was more than double in households with the poorest wealth quintile than in the richest counterparts, irrespective of the place of residence.The unsafe disposal practiceof child stoolwas predominantly higher among mothers who had no mass media exposure (76.8%), belonged to households with no water facility on the premises (74.3%),

Rural-urban difference in predictors of unsafe disposal practice of child stool
The present study reveals a notable rural-urban variation in the predictors of unsafe disposal practice of child stool (Table 3).For instance, mother's education, household wealth quintile, mass media exposure, sanitation, and region were identified as significant predictors of unsafe disposal practiceof child stool in both rural and urban areas.In contrast, mother's age, the water facility on household premises, religion, and social group were found to be significant predictors of unsafe disposal practice of child stool in rural areas only.Similarly, although geographical variance in predictors of unsafe disposal practice of child stool was found to be highest at the household level in both rural and urban areas, the level of variance was slightly higher in urban areas (4.42; 95% CI: 2.76-7.06)than in rural areas (4.00; 95% CI: 3.05-5.24)(Table 3).Increasing levels of mother's education, household wealth quintile, and mass-media exposure associate with a decreased probability of unsafe disposal practiceof child stool.In particular, mothers with higher education in rural areas had 42% (AOR:0.58;95% CI: 0.50-0.67)lower adjusted odds of unsafe disposal practice of child stool, while their urban counterparts showed a 36% (AOR:0.74;95% CI: 0.55-1.00)decrease compared to those with no formal education.Similarly, mothers from the richest household quintile were 84% (AOR:0.16;95% CI:0.12-0.20)and 87% (AOR:0.13;95% CI: 0.08-0..06-1.30) higher odds of unsafe disposal practiceof child stool, respectively than the general population.Households lacking water facilities on premises had a 31% (AOR:1.31;95% CI: 1.20-1.44)higher likelihood of unsafe disposal practice of child stool than their counterparts in rural areas.Regionally, central, east, and northeast areas displayed considerably higher adjusted odds of unsafe disposal practiceof child stool than their north region counterparts in both rural and urban areas.In rural areas, south and west regions exhibited significantly higher adjusted odds of unsafe disposal practiceof child stool compared to the north region.

Findings from decomposition analysis
The rural-urban gap in unsafe disposal practice of child stool was about 21 percentage points, which explained 80% of the overall difference (Supplementary Table3).In particular, the proportion of unsafe disposal practice of child stool in rural areas was 0.66, considerably higher than in urban counterparts (0.45).Household wealth quintile was examined as a key contributor to the rural-urban difference in unsafe disposal practice of child stool, explaining about 67% of the variance (Table 4).Household sanitation facilities (21.3%), mother's education (3.9%) and water facility on household premises (3.9%) were also identified as significant contributors to the rural-urban difference in unsafe disposal practice of child stool.

Discussion
The present study aims to contribute to the scientific literature by examining the rural-urban variation in prevalence and predictors of unsafe disposal practices of child stool among study participants in India, using the latest nationally representative sample survey data, i.e., NFHS-5 (2019-21).The study also explores the contributing factors of the rural-urban gap in unsafe disposal practices of child stool among the study participants.Existing studies have shown that the prevalence of unsafe disposal practices of child stool is higher in rural areas than urban counterparts in India 4,5 , using the third and fourth rounds of NFHS survey.However, these studies are failed to answering what the contributing factors are in this respective rural-urban gap 4,5 .Subsequently, the existing studies scientifically predicted the significant predictors of unsafe disposal practices of child stool at the national context but overlooked to contextualize rural-urban variation in these predictors 4,5 .In addition, a considerable number of prior studies have delved into the predictors of unsafe child stool disposal practices at the rural level in India [23][24][25] .Nevertheless, these studies, being micro-level analyses, fall short in providing insights into the broader macro-level context [23][24][25] .Therefore, the present study findings will be helpful to the research community, academia, and public health interest groups to understand the rural-urban dichotomy in prevalence, predictors of unsafe disposal practices of child stool, and associated contributors in India from the perspective of selected study participants.
The first and foremost finding of this study reveals a significant rural-urban gap in the prevalence of unsafe disposal practices of child stool observed in India, aligning with consistent trends identified in prior research 4,5 .While earlier studies acknowledged this gap 4,5,[23][24][25] , they inadequately explicated the key contributing factors to the rural-urban gap in unsafe child stool disposal practices.In contrast, the present study systematically identifies household wealth quintile, household sanitation facilities, water availability on household premises, and women's education as pivotal contributors to this specific rural-urban gap.The existing scientific literature emphasizes that issues such as household-level poverty, unimproved sanitation, or open defecation practices, along with the lack of household-level piped water connectivity and female illiteracy, are notably more prevalent in rural areas compared to their urban counterparts 2,17,22,26,27 .Consequently, the observed rural-urban differentials in unsafe child stool disposal practices may result of rural-urban gap in poor household wealth quintile, availability of improved sanitation facilities, access to water on household premises, and women's higher education.Beyond the quantifiable factors examined in this study, it is important to acknowledge the potential influence www.nature.com/scientificreports/ of numerous unobserved factors, including socio-cultural beliefs and practices, as well as an individual's health awareness 7,11,23,24,28 .Furthermore, the current study highlights a notable rural-urban gap in the prevalence of unsafe child stool disposal in most of the Indian states, particularly evident in Madhya Pradesh, Telangana, Gujarat, and Rajasthan.Conversely, Kerala, Mizoram, Sikkim, and several other states exhibit no such gap between rural and urban areas.Previous research has consistently highlighted wide rural-urban gaps in water and sanitation facilities and sociocultural indicators in states like Madhya Pradesh and Rajasthan, whereas such gaps are comparatively lower in Kerala 2,17,22,26,27 .Given this broader context, the rural-urban gap highlighted in our study may be influenced by these existing disparities.To comprehensively understand the reasons behind the state-level variations in the rural-urban gap in the prevalence of unsafe child stool disposal practices, further investigation is warranted.A state-wise analysis can provide valuable insights into the factors influencing this variation, making it crucial to consider states as the primary unit of study.
Secondly, household-level factors such as wealth quintile, sanitation, and water facilities were found to be significant predictors of child stool disposal practices among the study population.Consistent with earlier studies in India and elsewhere 2,4,5,12,23,24 , the study's findings affirm that improving household wealth parallels a decline in unsafe disposal practices.Improved household prosperity facilitates better living conditions, including upgraded sanitation facilities.As a result, better living conditions promote safe disposal services and practices 29 .In line with previous studies 4,5,30 , the practice of unsafe disposal of child stool was found to be prevalent among households with unimproved sanitation facilities or open defecation practices in the current study.Households with unimproved sanitation facilities and open defecation practices have no option to place child stool at safe places, for this reason, they throw it in open spaces or other unsafe places 31,32 .Similar to previous studies 4,5,22,[30][31][32] , water and improved sanitation facilities appeared as household factors influencing stool disposal practices.The current study explored that households lacking water facilities, especially in rural India, are prone to unsafe disposal.Prior research highlighted the significant role of water connectivity and improved sanitation facilities at the house for adult hygienic sanitation practices in India [22][23][24][25][30][31][32] ; the current study expands its significance for safely disposing of children's stools. It is rucial to consider these factors while formulating policies and interventions to promote safe disposal practices.
Thirdly, similar to previous studies in India 4,5,[23][24][25]30 and elsewhere 20,29 , individual-level factors such as mother's education and mass media exposure play a positive role in safe disposal practices of child stool. Pror studies suggest that higher-educated and mass media-exposed mothers are more aware of the associated risks of unsafe children's stool disposal, adopting safer behaviors and healthier lifestyles 33 .In Indian settings, mothers are the primary caregivers of children, and therefore, a significant linkage between mother's education and child health has been observed in many previous studies 33 . For istance, the risk of malnutrition and mortality among under-five children is more common among children with lower-educated mothers than their higher-educated counterparts [34][35][36] .The current study found that mother's age is an another individual-level factor of child stool disposal practices among the study participants, particularly in rural settings.In addition, the unsafe disposal practice of child stool is prevalent among teenage mothers in rural areas.Numerous scholarly investigations underscore the pressing issue of child marriage and early-age childbearing prevalent in rural India 37,38 .This societal concern predominantly affects individuals marked by low literacy levels and membership in economically disadvantaged households 37,38 .Consequently, mothers who undergo early-age childbearing, especially those with lower educational attainment and economic vulnerability 37 , may have limited awareness concerning the health risks linked to the unsafe disposal of child stool.Furthermore, the lack of improved sanitation facilities among child married women 38 , primarily due to household-level poverty, poses a significant barrier to following healthy lifestyle.It is crucial to consider these factors while formulating policies and interventions to promote safe disposal practices.
Fourthly, religious and social affiliations have emerged as substantial predictors of unsafe child stool disposal practices in the current study, specifically in rural areas.In particular, a higher likelihood of unsafe disposal was observed among mothers identifying with the Hindu religious group in rural areas, while no such significant risk was evident within the same religious group in urban areas.This highlights the nuanced influence of lifestyle over religion.The findings suggest that socio-cultural modernization may mitigate the impact of these factors on disposal practices in urban areas 39 .Despite the heterogeneity of urban spaces in terms of population and socio-cultural aspects, the rigidity of religious and caste affiliations weakens with modernity 39 .The current study also found that the probability of unsafe child stool disposal is higher among SC and ST communities compared to the general caste in rural areas, whereas it remained statistically insignificant in urban contexts.Numerous prior studies underscore the presence of social-group-based (caste-based) inequalities in household sanitation, water facilities, and socio-cultural prosperity, particularly pronounced in rural India as compared to urban counterparts 40 .In urban areas, disparities in living standards are primarily driven by individual socio-economic prosperity rather than caste identity.Although the association between social groups and child stool disposal practices holds significance in rural settings, it cannot be dismissed in the context of policy implications, given that nearly 70% of India's population resides in rural areas 17 .The conclusive finding of the current study suggests a slightly higher household-level variance in unsafe child stool disposal practices in urban areas compared to their rural counterparts.This elevated household-level variance in urban areas may be attributed to the more pronounced household-level inequality in sanitation practices within urban settings 22,41 .Notably, a significant number of urban residents utilize community toilets situated at a considerable distance from their households 41 , which may discourage the regular disposal of child stool in the toilet.Instead, it is common for urban residents opt for easily accessible door-step dustbins.

Strengths
The study has several some strengths.Foremost, the present study filled existing research gap by contextualizing rural-urban variation in the prevalence and predictors of unsafe child stool disposal practices in India.Furthermore, the study used nationally representative sample survey data, i.e., the NFHS, which minimized the risk of sampling errors in area-specific (rural vs. urban) study findings.

Limitations
Notwithstanding its strengths, this study has certain limitations that warrant consideration.As a cross-sectional study, establishing a causal relationship between outcomes and independent variables remains challenging.Secondly, the reliance on self-reported data introduces the possibility of both social desirability bias and recall bias, compromising the absolute accuracy of the findings.Thirdly, it's important to note that the study's depiction of prevalence and predictors is based on the period of the survey and, at the present moment, inadvertently failed to capture the usual disposal practice of child stool.Fourthly, due to the quantitative data structure of NFHS, several qualitative nuances such as cultural norms, habits, and beliefs were missed in the study.Lastly, the present study overlooked the association between unsafe disposal practices and child health outcomes, therefore, recommends further study to investigate it.

conclusion, this study provides valuable insights into the rural-urban disparities in unsafe disposal practices of child stool among study population in India.The significant rural-urban gap underscores the importance of tailoring interventions to address specific contextual factors influencing child stool disposal practices.Household-level factors such as wealth quintile, sanitation facilities, water availability, and women's education have emerged as key contributors to this gap.Policies aimed at improving these factors in rural areas could substantially reduce unsafe disposal practices.Concurrently, policies promoting economic prosperity and enhancing sanitation infrastructure at the household level can significantly contribute to safer practices.Furthermore, emphasizing the role of maternal education and mass media exposure is crucial in fostering awareness and promoting healthier behaviors in child care.The state-level variations emphasize the need for targeted strategies, acknowledging the diverse socio-economic and cultural landscapes across different regions of India.States exhibiting wider rural-urban gaps, such as Madhya Pradesh and Rajasthan, require focused interventions to address existing disparities in water and sanitation facilities.On the other hand, states like Kerala, where the gap is minimal, can serve as models for successful policies that bridge rural-urban differentials.Religious and social affiliations were identified as significant predictors, particularly in rural areas.Understanding the nuanced influence of lifestyle over religion and the impact of socio-cultural modernization is vital for tailoring interventions that consider the evolving dynamics in urban areas.The study underscores the need for holistic policies addressing the rural-urban gap in child stool disposal practices, taking into account the multifaceted influences at the household, individual, and societal levels.By integrating these findings into public health interventions, policymakers can work towards fostering safer and healthier practices for child stool disposal, contributing to the overall well-being of the population.
